Abstract
The present disclosure is directed to a novel apparatus and novel methods for the separation, characterization, and manipulation of matter. In particular, the invention combines the use of frequency-dependent dielectric and conductive properties of particulate matter and solubilized matter with the properties of a suspending medium to discriminate and separate such matter. The apparatus includes a chamber having at least one spiral electrode element. Matter is separated in the chamber by a dielectrophoretic (DEP) force caused by the energized electrode or electrodes.
